My invention relates to shelves and ana-l- `ogous structures, and especially to knock down shelves which are very strong and rigid when set up and arranged for use, and" which may be easily and quickly taken apart, arranged very compactly for transportation7 and easily and quickly reassembled.

The characteristics, objects and advantages of the invention are sufficiently ei;- plaine-d hereafter, in connection with the detail description of the accompanying drawings, which show one exemplifying structure embodying the invention. This particular embodiment of the invention is what l call a corner shelf, in distinction from a straight shelf disclosed in a companion application. After considering the present embodiment of the invention, slrilled persons will understand that many variations may be made without departing from the invention, and l contemplate the employment of any structures that are properly within the scope of the appended claims.

Fig. 10 shows one compact arrangement of the parts knocked down for shipment.

This shelf is .especially designed to be supported in a wall corner as shown in Fig. 1, where the walls join at a right angle as usual. lThe shelf structure comprises the vtwo ma'n or shelf sections proper, 1 and 2,

an interlocking member or connector 16, and

rear or supporting members 24 and 2r. The

parts may be made of various materials, but

it is usually preferred to make them of .a strong light metal, or metallic alloy, of lwhich yclnraioinin is one example. The parts may be produced of such alloys by die casting methods in r pid and economical fashion, and with complete .or vnearly complete STRUCTURE.

elimination of any machining operations. The parts may also be made of moderate cross-section and at the same time are very strong, rigid and practically indestructible. 'lhe shelf sections preferably are in the form of Iequilateral triangles, and `when placed together with the edges 6 and 7' in contact as shown in 1, they form another' equilateral triangle, fitting the wall 65 corner and of any desired or reasonable depth. The adjacentedges of the shelf sections are intei'loclred by formations conveniently called tongue and groove formations,

including a tongue 8 projecting from the 70 edge 6 of section 1 and of clcroes section to co-operate with a groove 9 yof similar crosssection` in the edge of section 2. The tongue 8 extends from one corner of its shelf section to a point substantially distant from the front shelf edge 10, and the groove 9 is similarly dimensioned. These parts are connected in the manner indicated in Fig. 8 by inserting the end 11 of tongue@ in the rear end of the groove 9 and moving shelf 30 .section 2 relative to section 1, as indicated by the arrow, Fig. 7, until the end 11 of tongue 8 encounters the end of groove 9. rEhe front shelf edges 10 and 12 are then in line. rlhe shelf sections are additionally connected or interloclred by T-section tongues or ribs 14 on the lower shelf faces adjacent and parallel the edges 6 and These ribs extend from the front shelf edges to points substantially distant from the rear corners 15. To co-operate with these ribs, a connector or interlocking member lois provided, which has parallel grooves 17 of ll'section to lit the ribs lll. 'lhe rear corners of this rectangular connector are cut away forming angular or beveled faces 18, later referred to. After the shelf sections have been interconnected, as above explained, the connector 16 applied to the end shelf. sui'- faces and moved ,forxfard from the rear, so that the rear ends of the ribs 14 enter the front ends of grooves l?. 'lhe connector is stopped in the proper position with its front end in line with the front shelf edges by the engagement of the rear ends o f the ribs with the rear ends of'channels 17.

' rlhe .shelf sections 1 and 2 also have on their lower faces adjacent and parallel the edges 20, tongues 21 and 22 respectively of llsection, exten-ding from the front edges 10 110 and 12 to points well removed fromvthe rear y corners 15. rlhe tongue 21 cooperates-with 3. A corner shelf structure comprising two substantially triangular shelf sections, provided with slidably engaged interlocking tongue and groove formations at adjacent sides whereby the sections may be detachably connected t-o form a composite triangular shelf, and supporting members having groove formations slidably engaged with interlocking tongue formations `adjacent diagonally disposed edges of the respective shelf sections, one of the supporting meinbers having a portion overlapping the rear end of the other.

l. A corner shelf structure comprising two substantially triangular shelf sections, provided with .slidably engaged interlocking tongue and groove formations at .adjacent f sides whereby the sections may be detachably connected to form a composite triangular shelf, and supporting members having groove formations slidably engaged with interlocking tongue formations adjacent diagonally disposed edges of the respectiveshelf sections, the parts being readily disconnectible by rearward sliding movement of respective parts and being dim-ensioned for packing in a space whose greatest dimension is substantially no greater' than one-half the greatest linear dimension-of the composite shelf when set up for use.
